Micro-Welding of Nitinol Shape Memory Alloy
(University of Waterloo, 2010-04-30)Nitinol shape memory alloys have revolutionized many traditional engineering designs with the unique properties of pseudoelasticity and shape memory effect. At the present moment, primary fabrication processes for ... -
Microbial communities of wastewater in the Canadian Arctic
(University of Waterloo, 2020-01-20)Wastewater management in the Canadian Arctic is challenging due to the extreme climate and lack of conventional treatment system infrastructure. To resolve these issues, most Northern communities use waste stabilization ... -
Microbial Community Compositional Stability in Agricultural Soils During Freeze-Thaw and Fertilizer Stress
(University of Waterloo, 2024-01-22)Microbial activity persists in cold region agricultural soils during the fall, winter, and spring (i.e., non-growing season) and frozen condition, with peak activity during thaw events. Climate change is expected to change ... -
Microbial Composition and Functional Diversity in Waste Environments
(University of Waterloo, 2023-01-09)Landfilling remains the most common endpoint of discarded waste. At landfill sites, waste is transformed and degraded by microbially mediated processes conducted by different trophic groups, comprised of members of a ... -
Microbial diversity and cellulosic capacity in municipal waste sites
(University of Waterloo, 2019-01-25)Cellulose is the most abundant organic compound found on earth. Cellulose’s recalcitrance to hydrolysis is a major limitation to improving the efficiency of industrial applications. The biofuel, pulp and paper, agriculture, ... -
Microbial ecology of ammonia oxidation in the Grand River
(University of Waterloo, 2014-08-28)The Grand River is the largest catchment in Southern Ontario and is heavily impacted by the results of human activities, including wastewater effluent and agricultural and urban runoff. Ammonia oxidation is an important ... -
Microbial Ecology of Phototrophs in Iron-rich Boreal Shield Lakes
(University of Waterloo, 2020-09-24)The early Earth oceans of the Archaean Eon (approx. 3.8-2.5 billion years ago) are thought to have been predominantly anoxic with ferruginous waters containing high levels of dissolved ferrous iron and low levels of sulfate. ... -
Microbiology of Barrier Component Analogues of a Deep Geological Repository
(University of Waterloo, 2020-09-18)Many countries are in the process of designing and implementing long-term storage solutions for used nuclear fuel. Like many of these countries, Canada is considering a deep geological repository (DGR) wherein used fuel ... -
Microbiology of Bentonite Clay
(University of Waterloo, 2020-09-25)Highly compacted bentonite clay has been proposed as an important engineered barrier component of a deep geological repository for Canada’s high-level nuclear fuel waste. As a result, the microbiology of bentonite clay is ... -
Microclimatic Effects of Forest to Peatland Transitions Within the Boreal Plains
(University of Waterloo, 2019-04-30)Peatlands cover approximately 50% of the total landscape of the Western Boreal Forest, which includes the sub-humid Boreal Plains (BP) ecozone. The BP experiences persistent water deficit conditions, promoting anaerobic ... -
Microcolony Dynamics: Motion from Growth, Order, and Incompressibility
(University of Waterloo, 2023-04-27)Rod-shaped bacteria such as E. coli reproduce by expanding along their long axis and splitting into pairs of daughter cells. If conditions are favourable for growth, they will continue in this way, doubling repeatedly until ... -
Microcystin and Microcystis Destruction by Ozone in Drinking Water Treatment: Constraints and Effects
(University of Waterloo, 2016-07-14)Appropriate and effective drinking water treatment is critical to the protection of public health. Toxic cyanobacterial blooms are a globally increasing drinking water source quality-associated health risk as even very ... -
Microcystin in Ugandan lakes: Production dynamics, accumulation in fish, and risk evaluation
(University of Waterloo, 2010-12-23)Eutrophication of freshwater lakes has led to an increase in the occurrence of harmful cyanobacterial blooms, and it is expected that a warming climate will further exacerbate the frequency and duration of such blooms. ... -
A Microeconomic Perspective to Infrastructure Renewal Decisions
(University of Waterloo, 2014-12-16)Under the prevailing financial constraints and rapid infrastructure deterioration, funding decisions for renewal (rehabilitation) projects have become large challenges for engineers and economists alike. However, existing ... -
